Just remember that string comparison like "x" > "X" is case-sensitive

<pre><code>"aa" &lt; "ab" //true
"aa" &lt; "Ab" //false
</code></pre>

You can use <code>.toLowerCase()</code> to compare without case sensitivity.

blocks|key|377662|text|您确实说过比较是为了排序的目的。那么我建议使用localeCompare：|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|377663|"a".localeCompare("b");|code-block|syntax|javascript|377664|如果返回"a"+<+"b"、1或0，则返回-1，否则返回Array.prototype.sort()|style|CODE|377665|请记住，排序依赖于区域设置。例如，在德语中，ä是a的变体，因此"ä".localeCompare("b",+"de-DE")返回-1。在瑞典语中，ä是字母表中的最后一个字母，因此"ä".localeCompare("b",+"se-SE")返回1。|377666|如果没有为localeCompare设置第二个参数，则使用浏览器的区域设置。在我的经验中，这从来不是我想要的，因为它将与服务器不同地排序，服务器为所有用户提供固定的区域设置。|377667|此外，如果要排序的内容包含数字，则可能需要：|377668|"a5b".localeCompare("a21b",+undefined,+{+numeric:+true+})|377669|这将返回-1，识别出5作为一个数字小于21。如果没有{+numeric:+true+}，它将返回1，因为"2“在"5”之前排序。在许多实际应用程序中，用户期望"a5b“出现在"a21b”之前。|377670|entityMap|0|LINK|mutability|MUTABLE|url|https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String/localeCompare|1|https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/sort^0|N|D|0|0|0|4|9|E|1|G|1|L|2|S|M|1|0|M|1|O|1|V|V|1S|2|21|1|2H|V|3E|1|0|5|D|0|0|0|Q|H|0^^$0|@$1|2|3|4|5|6|7|16|8|@]|9|@$A|17|B|18|1|19]]|C|$]]|$1|D|3|E|5|F|7|1A|8|@]|9|@]|C|$G|H]]|$1|I|3|J|5|6|7|1B|8|@$A|1C|B|1D|K|L]|$A|1E|B|1F|K|L]|$A|1G|B|1H|K|L]|$A|1I|B|1J|K|L]]|9|@$A|1K|B|1L|1|1M]]|C|$]]|$1|M|3|N|5|6|7|1N|8|@$A|1O|B|1P|K|L]|$A|1Q|B|1R|K|L]|$A|1S|B|1T|K|L]|$A|1U|B|1V|K|L]|$A|1W|B|1X|K|L]|$A|1Y|B|1Z|K|L]|$A|20|B|21|K|L]]|9|@]|C|$]]|$1|O|3|P|5|6|7|22|8|@$A|23|B|24|K|L]]|9|@]|C|$]]|$1|Q|3|R|5|6|7|25|8|@]|9|@]|C|$]]|$1|S|3|T|5|F|7|26|8|@]|9|@]|C|$G|H]]|$1|U|3|V|5|6|7|27|8|@$A|28|B|29|K|L]]|9|@]|C|$]]|$1|W|3|-4|5|6|7|2A|8|@]|9|@]|C|$]]]|X|$Y|$5|Z|10|11|C|$12|13]]|14|$5|Z|10|11|C|$12|15]]]]

You do say that the comparison is for sorting purposes. Then I suggest <a href="https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String/localeCompare" rel="noreferrer">localeCompare</a> instead:
<pre><code>&quot;a&quot;.localeCompare(&quot;b&quot;);
</code></pre>
It returns <code>-1</code> since <code>&quot;a&quot; &lt; &quot;b&quot;</code>, <code>1</code> or <code>0</code> otherwise, like you need for <a href="https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/sort" rel="noreferrer">Array.prototype.sort()</a>
Keep in mind that sorting is locale dependent. E.g. in German, <code>ä</code> is a variant of <code>a</code>, so <code>&quot;ä&quot;.localeCompare(&quot;b&quot;, &quot;de-DE&quot;)</code> returns <code>-1</code>. In Swedish, <code>ä</code> is one of the last letters in the alphabet, so <code>&quot;ä&quot;.localeCompare(&quot;b&quot;, &quot;se-SE&quot;)</code> returns <code>1</code>.
Without the second parameter to <code>localeCompare</code>, the browser's locale is used. Which in my experience is never what I want, because then it'll sort differently than the server, which has a fixed locale for all users.
Also, if what you are sorting contains numbers, you may want:
<pre><code>&quot;a5b&quot;.localeCompare(&quot;a21b&quot;, undefined, { numeric: true })
</code></pre>
This returns -1, recognizing that 5 as a number is less than 21. Without <code>{ numeric: true }</code> it returns 1, since &quot;2&quot; sorts before &quot;5&quot;. In many real-world applications, users expect &quot;a5b&quot; to come before &quot;a21b&quot;.

blocks|key|377712|text|"a".localeCompare("b")实际上应该返回-1，因为a在b之前排序|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|377713|http://www.w3schools.com/jsref/jsref_localecompare.asp|377714|entityMap|0|LINK|mutability|MUTABLE|url^0|0|M|T|2|Y|1|10|1|0|0|1I|0|0^^$0|@$1|2|3|4|5|6|7|O|8|@$9|P|A|Q|B|C]|$9|R|A|S|B|C]|$9|T|A|U|B|C]|$9|V|A|W|B|C]]|D|@]|E|$]]|$1|F|3|G|5|6|7|X|8|@]|D|@$9|Y|A|Z|1|10]]|E|$]]|$1|H|3|-4|5|6|7|11|8|@]|D|@]|E|$]]]|I|$J|$5|K|L|M|E|$N|G]]]]

Lets say that we have an array of objects:

<pre><code>{ name : String }
</code></pre>

then we can sort our array as follows:

<pre><code>array.sort(function(a, b) {
 var orderBool = a.name &gt; b.name;
 return orderBool ? 1 : -1;
});
</code></pre>

Note: Be careful for upper letters, you may need to cast your string to lower case due to your purpose.

I'm trying to compare 2 strings alphabetically for sorting purposes. For example I want to have a boolean check like <code>if('aaaa' &lt; 'ab')</code>. I tried it, but it's not giving me correct results, so I guess that's not the right syntax. How do I do this in jquery or Javascript?

comparing 2 strings alphabetically for sorting purposes

我正在尝试按字母顺序比较两个字符串，以便进行排序。例如，我希望有一个像if('aaaa' < 'ab')这样的布尔检查。我试过了，但它没有给我正确的结果，所以我猜这不是正确的语法。我如何在jquery或Javascript中做到这一点？
